In my region, salary lotteries are very popular in many workplaces. I don't know what's the exact English term for his but we call it that name. The purpose of salary lottery is that 5-6 employees collect together and they play lottery. The first winner gets the salary of every worker, in the next months the second winner gets everyone's salary and that's it. There isn't a random winner, everyone gets their salary back but the fate of who is the first person to receive the salary is decided via a simple coin flip.
Sounds like a pyramid scheme to be honest lol. Might not be but it sounds unnecessary and inconvenient to me. It is fair in a way that the person chosen is through coin flip and not based on personal whims.
You may ask me how do they live for 6 months without a salary? Family members take care of them.
Then what is the point of working? You work because you have bills to pay every month and every day. How annoying it would be to only have money 2x a year. I find it hard to find benefits of participating in this.
